BUMPER.

Application led February 20, 1928.

This invention relates to vehicle bumpers and more particularly to a pivotal construction :lor connectingl the bars ci a bumper and an object ci the invention is to provide a `pivoted connection which may be more con veniently and economically constructed and assembled. It is a. iifiilrther object to produce such a construction which, at the same time, will present a more attractive appearance. A further object to provide a plate at the point o'l connection ot the bars7 which plate will allow a pivotal action of the bars relative to each other and which will improve the aijipearance of the bumper. A. further object is to provide an orimmental plate which will cooperate with a pin in pivotally counectingthe bars of the bumper.

Further and more or less limited objects will. he apparent from the olowinn; description7 from the drawings, and from the use oit the articles covered by the appended claims.

limit the application of my invention to any particular position relative to the bumper or to the vehicle. i

Oi the several reference characters, l and. 2 denote the upper and lower impact bars, resi ectively7 of a bumper of the general type shown in hlctiregor Patent No. 1,372,154, issued lli/larch 22j 192i, wherein a rear bar 3 is pivotally connected at.' ends to the ends oi." the impact bars and is connected at its central portion to the central portion oit the impact section by means oi? the clamp el Each oit" the impact bars l and Qhas an eye 5 at cach end, and at each end of the rear bar 3 there is fastened an end connector li which is provided with a hori'v/.ontally projccting portion i, having an aperture therein, adapted to extend between the eyes of the impact bars. A pin 8 passes through the aligned eyes 5, 5 and the aperture in the portion 7 cit' the end comiector (i to pivotal ly conncct the .impact and rear bars.

A mask plate 9 is clamped to the lront sur- 'faces oit the impact bars at each end oit the bumper. This plate is adapted to bear upon the liront surfaces oit the impact bars and has rearward ly extern-linkev 'flanges ll), l() at the top and bottom adapted to extend over the edges ot the bars and to cover the eyes at `the ends thereof. rllie impact bars are here shown as cut down at ll. a distance equal :to the thickness oit the flanges 10, l0 in oriflerto provide a smooth line in. the outline oi the bumper. Such shaping may be omitted or may be varied to suit the particular configuration desired.

rlhe outer end of each mask plate 9 extends to a point lll (i) beyond the end ot the impact bars and so provides a bearing surface which will prevent inward longitudinal movementvoii the mask plate on the impact bars. A lug l2 projects iironi the inner surn iace of the mask plate 9, extei'iding between. the impact bars and providing` a bcariiw surface which will prevent outward longitudin al movement ci? the plate. There is an aperture 13 through the plate 9 and a lug` .14 n'iay project from the rear surface of the plate on each side of this apertme,such lugs may cX- tend through between the impact ba rs and will then prevent the rotation oit the rear clamp plate l5. A bolt '1.6 passing throughfthe aperture in the mask plate 9, through the rear plate and between the impact bars 1 and 2 serves to d-raw the front and rear clamp plates together.

In the modified form of my invention shown in Figs. 5, 9 and 10, the impact bar 1fL is shown as cut down at 11a to a greater extent and having an eye 5a which is shorter. VThe mash plate 9a is shaped at 18 to form a curve ot the desired shape at the end of the bumper and is adapted to bear upon the front surfaces of the impact bars. The iiange 1OfL extends rearwardly from the mask plate to cover the lower end of the eye at the end of the impact bar 21k A substantially horizontal projection 17, extending irom the inner surface of the mask plate, is adapted to cover the upper sui-tace ofthe eye 5n and bear thereupon. The bolt 1G passing through the front plate 9, the rear plate 15, and between the impact bars 1 and 2, serves to draw these plates toward -each other. It is apparent that both the top and the bottom of the mask plate 9L could be curved it such a conliguration were desired, suitable projections, such as 17, being provided to prevent the downward movement of the pin Su.

kThe bars are assembled by placing the apertures in the end connectors on therear bar in alignment with and between the upper and lower spaced impact bars. The pin is then inserted in the eyes and in the aperture in the end connector and washers 19, of telt or other suitable material, may be placed at the ends of the pins to prevent movement or rattling thereof. The mask plate is then applied and the bolt 16 is tightened to hold the mask plate in posit-ion. The projecting fianges 10, 1() or' 10a and 17 prevent the withdrawal of the pins from the eyes.y

In the modification shownv in Figs. 11 and A12 a wedge shaped block 2O having slanting faces 21 and an aperture 22, is used tomore rigidly hold the barsfl and 2 in proper spaced relation'. The bolt 16 passes through the aperture 22 and the pressure of the nut at the end of the bolt forces the bars 1 and 2 apart and against the upper and lower flanges of the plate 9, thereby reducing the tendency to rattle. The block may be of ,a somewhat different shape and may havevertically extending shoulders adapted to bear upon'the rearsurfaces of the bars 1 and 2 in their vertically spaced positions. It is apparent that this wedge shaped block could be used in place of the'plate 15 with either of the front plates shown.v

It is apparent that my invention may be appliedv to bumpers of different construction and to different portions of the bumper and it is also apparent that various modiiica.- tions may be made in the details of construction without avoiding my invention in its broader scope. For instance, suitable equivalents may be substituted for the eyes at the ends ofthe impact Vbars or vthe end connectors 1.
